looking good, hope things go good.

Nice!

What is the expected drop altitude?

Are you using an RC control link also?

Comment by Earl on July 30, 2012 at 12:13pm

Drop for first flight <5000 Ft to test everything. Yes RC as well as Mission planner. Hope to use MP only. Delay may be a problem. But the APM will fly it and do RTL and Landing. All the hard stuff I am not good at.

We will have a FPV camera in the nose with the 5 watt video transmitter.

Have you super reinforced that X8 I hear tell that they like to flap like a bird. I guess your one is reasonably light though without power system and motor, 10watts on 2m are you trying to hot wire cut the wing ;-) For sure people will hear it miles and miles away. Best of for the next try.

A little clarification on how wire rope cutter.

why dont you try something Like spiderwire for your cordage very fine and very strong melts in ms with your nicrome cutter. much less load to release I used something similar to release some underwater sensors

Just posted this over on AeroBalloon forum, forgive double posting but may be helpful here . . . On high altitude balloon projects to avoid Arduino flight computer failures due to outside systems, for example, cutdown, communications, or sensor controllers from getting stuck in a subroutine, watchdog timer within Task Scheduler for Arduino will reset the flight computer. Source: Hack a Day

Great work by they way.....

I live in the Key and have wanted to drop something like this into a hurricane for years as they go by my house...

the nice thing about the braided fishing line (spiderwire) you can get it as low as 5 to 10 lbs for tournament certified line...

Comment by Kevin Brown on July 30, 2012 at 3:35pm

No problem, I understand the max load limit

from the looks in the photo it looks like a very beefy cutter, with a very large dia. wire and very long = massive load

and long heat time. sized right a button cell could drop a 300 lbs load no problem because of the dia. of the spiderwire is so thin hair size
